Abstract
Example plasmaclave devices are shown for using a plasma to sterilize objects or equipment (e.g., medical instruments, surgical devices, food preparation utensils, etc.) placed inside the plasmaclave devices. In some embodiments, the plasmaclave device includes fixed magnets, steering coils, and a high voltage electrode for generating a plasma field and controlling where the plasma field is focused, so that the plasma field is rapidly scanned over a target surface. In some embodiments, the plasmaclave device includes a high voltage coil, a motor, and a blade electrode for generating a plasma field and spinning the blade electrode, so that the plasma field is rapidly scanned over a target surface.
Claims19
A plasmaclave device used to sterilize objects, comprising:
- a chamber;
- a stationary tray disposed within the chamber, the stationary tray having a target surface and being configured to hold the objects on the target surface;
- a constrained plasma zone within the chamber adjacent to the target surface of the stationary tray;
- one or more high voltage electrodes disposed within the chamber;
- fixed magnets disposed within the chamber;
- and
- steering coils disposed within the chamber;
- wherein:
- the high voltage electrodes generate an electric field that creates a plasma within the chamber;
- the fixed magnets focus the electric field constraining the plasma into the constrained plasma zone of the of the chamber;
- and
- the steering coils further constrain the plasma, and scan the further constrained plasma over the target surface of the stationary tray.
A method of sterilizing objects, comprising:
- providing a chamber having a stationary tray and a constrained plasma zone therein, the objects being on a target surface of the stationary tray;
- creating a plasma within the chamber by generating an electric field therein;
- pulsing the plasma at a repetition frequency using a power supply;
- constraining the plasma into the constrained plasma zone by focusing the electric field using fixed magnets;
- and
- further constraining the plasma and scanning the further constrained plasma across the objects on the target surface of the stationary tray using steering coils.
